HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Fixes an issue seen in CLSM that causes a diskgroup import to fail when clsm
collision proposals are seen in messages file.
• Fixes a LSM diskgroup deport problem.
• Prevents a "Too Many Volumes" error when attempting to add a volume and the
maximum volumes allowed has not been reached.
• Fixes an issue with the initialization of large disks.
• Fixes an issue seen when using KZPAC/SWXCR disks in LSM.
• Corrects several label strings in the SysMan LSM application.
• Fixes problems with SysMan LSM administrator that deal with disk names in "Add
disk to LSM" window and the display of disk names in Migrate.
• Allows the LSM voldisk online and voldisk -a online commands to work
cluster-wide for devices that have not been replaced. This is useful for rescanning
devices that had a temporary disk failure.
• Corrects several potential security vulnerabilities where, under certain
circumstances, system integrity may be compromised. These may be in the form
of improper file access.
• Corrects a problem in which volmigrate returns a shell error when attempting to
migrate an AdvFS domain with multiple filesets. These domains can now be
migrated as long as all the filesets are mounted.
• Prevents inconsistent LSM volumes when the name of a partition that is being
encapsulated matches the name of a current LSM volume.
• Corrects a problem in which smsd triggers LSM configuration errors when querying
LSM in a cluster. This fix ensures that a cluster member will be up to date with
respect to the LSM configuration when calls are made to an internal LSM routine.
• Corrects a problem during the creation of a new plex in which the volmake
command reports that associating a subdisk with the plex would cause an overlap
with another subdisk when they should not be overlapping.
• Prevents vold from core dumping when attempting to delete a disk that was not
initialized properly.
• Provides protection against a class of potential security vulnerabilities called buffer
overflows. Buffer overflows are sometimes exploited in an attempt to subvert the
function of a privileged program and possibly execute commands at the elevated
privileges if the program file has the setuid privilege. This patch allows a system
administrator to enable memory management protections that limit potential
buffer overflow vulnerabilities.
• Corrects an I/O performance issue that occurs when CLSM is configured and one
member of a cluster goes down unexpectedly.
• Fixes a slow boot when booting several cluster nodes at the same time and CLSM
is configured.
• Enables volassist to create a mirror of a striped volume with the mirror having a
layout of concat.
